这篇文章讨论了一个实验的可能性，在多轴度的影响，环境温度下的速率依赖性和其在静水压力下的行为方面的泡沫橡胶。在此背景下，示例性地研究了基于乙烯丙烯二烯单体的混合开孔和闭孔橡胶。本文旨在对这种特殊类型的材料的表征方法和相当大的影响给出一个总体概念。重点介绍了实验过程和所使用的测试设备，并结合真三维数字图像相关等分析方法。考虑到结构的可压缩性的材料模型的方法，使用多孔介质理论与附加的温度依赖性。
This contribution discusses an experimental possibility to characterise a cellular rubber in terms of the influence of multiaxiality, rate dependency under environmental temperature and its behaviour under hydrostatic pressure. In this context, a mixed open and closed cell rubber based on an ethylene propylene diene monomer is investigated exemplarily. The present article intends to give a general idea of the characterisation method and the considerable effects of this special type of material. The main focus lies on the experimental procedure and the used testing devices in combination with the analysis methods such as true three-dimensional digital image correlation. The structural compressibility is taken into account by an approach for a material model using the Theory of Porous Media with additional temperature dependence.
